Subject: added support for showing arrays and aliases to the var method, but array elements... 
X-Git-Tag: 2.140.90~631
X-Git-Url: https://feistymeow.org/gitweb/?a=commitdiff_plain;h=2c8ab3825d321561c22e4759ed7d70d9bc50877e;p=feisty_meow.git

added support for showing arrays and aliases to the var method, but array elements are not distinguished yet by internal quoting (so it can be confusing if array had elements with spaces).  but it looks pretty good and basically works.
